MACHINE FOR PRODUCING SEAMLESS BODIES, SWEETMEATS, AND OTHERS FROM PLASTIC MASSES Filed June 2, 1926 2 Sheets-Sheet 2 Patented Apr. 8, 1930 v PONISCH, OF LEIPZIG-LEUTZSCH, GERMANY MACHINE FOR PRODUCING SEALMLESS BODIES, SWEETMEATS, AND OTHERS FROM PLASTIC Application filed June 2, 1926, Serial No.

Machines for the production of sweetmeats without seam, so called rolling machmes, have become known. They comprise rolls which cooperate in pairs or at three. The string of sugar is out outside the machme to a length corresponding to the length of the rolls thrown between the rolls and rolled by slow pressing together of the rotating rolls to form seamless sweetmeats. Besides this working method an older method exists in which the rolled sweetmeats are manufactured with the aid of plates which have molding grooves in accordance with the size and shape of the sweetmeats to be made. These plates work always in pairs. The string of sugar is out according to the length of the plates inserted by hand between the plates and rolled to form seamless sweetmeats by a reciprocating movement of the top plate in the direction of the molding grooves. Both these methods possess serious inconveniences. The string of sugar must be inserted by hand and waste is not to be avoided. 3 to 4 persons are required to attend to the machine.

This invention has for its object to avoid these inconveniences by an improved machine in which an endless string of sugar is transformed, without waste, into seamless rolled sweetmeats. This problem has been solved in a manner which will be hereinafter described.

The older method of manufacturing rolled sweetmeats between grooved plates seems to be best for this purpose. It is merely necessary to form endless rows of plates and to connect the same with one another after the manner of chain links. The plate-chains which are thus formed are stretched each over two drums so that an upper and a lower plate-chain are obtained the elements of which cooperate pairwise. The drums are driven by toothed wheels which move the plate-chains so that they converge at the point where the sugar string enters between the plate-chains but diverge at the point at which the rolled sweetmeats are discharged from between the plate-chains. The molds for the sweetmeats .are cut into the plates transversely to the direction of movement of MASSES 113,263, and in Germany June 15, 1925.

the chains. Plate-chains of similar type, the elements or links of which cooperate in a similar manner, have become known for cutting and pressing of sugar strings.

In order to roll theportions of the sugar string, which has been indented by the molding grooves, the chains are further shifted in transverse direction so that the transverse shifting movement of the top plate-chain is in opposite direction to that of the bottom plate-chain.

The operation is as follows :The sugar string is gripped by the edges of a groove at theadmission point where the plates come together and is gradually indented, and rolled by the transverse shifting movement of the plates and conveyed at the same time. In this manner the endless sugar string is rolled to form seamless sweetmeats. The shifting movement in transverse direction might be limited to one of the two platechains, the other plate-chain executing only a continuous movement in longitudinal 'direction.

It is evidently also possible to carry out the longitudinal and transverse movements of the plate-chains not simultaneously but at different times, a corresponding transmission gear being inserted. In this case the sugar string will be fed to the machine by engaging the drums to rotate in one certain direction whereupon, owing to a subsequent transverse movement of the plate-chains the sweetmeats are rolled. In this arrangement it would, however, be necessary that the upper platechain, after the conveying of the sugar-string, descends gradually in carrying out at the same time a transverse shifting movement.

For the production of sweetmeats of simple shape, for instance ballor egg-shape and the like, two drums might be substituted for theplate-chains, the molding grooves being cut into the surfaces of the drums in the direction of the generating lines. The operation would be the same as described above. The rotating drums grip the sugar string, from which, by the transverse movement of the drums, sweetmeats are rolled in accord- .ance with the cross section of the molding grooves.

There is further the ossibility to make one plate-chain work togetlier with one drum this arrangement possessing the advantages to be cheaper than two plate-chains and to offer a larger rolling-surface than two drums, so that the output is increased.

Several embodiments of the invention are shown, by way of example, in the accompanying drawing, in which: v

Fig. 2 is a side elevation, partly in sectlon.

Fig. 3 is a section on line IIIIII of 1.

Fig. 4 is a section on line IVIV of Fig. 2.

Fig. 5 shows a simple form of construction according to which only the upper platechain executes a transverse movement.

Fig. 6 is a side elevation of Fig. 5 in section.

Figs. 7 and 8 are similar views as Figs. 5 and 6 showing a machine composed of two drums.

Figs. 9 and 10 are similar views as Figs. 5 and 6 showing a machine composed of one plate-chain and one drum.

As shown in Figs. 1 and 2 the four drums 1, 2, 3, 4 serve to guide each pair of platechains, consisting of plates 5, 6 respectlvely. Into the upper surfaces of the plates 5 and 6 molding grooves 7 are cut. The longitudinal direction in which the plate-chains move is indicated by the arrows in Fig. 5 which indicate the direction of rotation of the drums 1 and 2. The sugar string 8 enters at 9 into the machine and it is molded by the plate-chains 5 and 6 and rolled to form sweetmeats which are discharged from the machine at 10 in finished state.

The side elevation Fig. 2 shows mainly the driving elements for producing the transverse movement of the plate-chains 5 and 6. The drums 3 and 4 are shown in their extreme osition displaced the one with regard to t e other. The arrows indicate the movement in opposite directions. The connecting rods 11 and 12 connected by means of sliding links 13 and 14 with the drums 3 and 4 serve for communicating to said drums 3 and 4 a movement in opposite directions. The connecting rods 11 and 12 are driven from a rod 16 pivotally mounted on a pivot axle 15 and connected, by means of a connecting rod 17 with an eccentricor crank-gear 25 which is driven from bevel wheels 28 keyed on a shaft 27. This shaft 27 is driven by a belt pulley 26.

The rotating movement of the drums 3 and 4 is effected by means of gear wheels 18 and 19. 20 is the vertical frame of the machine. The drum 3 is keyed on a shaft 22 and the drum 4 on a shaft 21. The gear wheels 18 and 19 are driven by a spur wheel 29 keyed on shaft 27.

According to the form of construction shown in Figs. 5 and 6 the transverse reciprocating1 shifting movement is limited to the upper p ate-cham 5 as only the drums 1 and 3 are coupled with the pull rod 12 which is controlled by a lever 16, the drums 2 and 4 being not coupled with this lever.

Figs. 7 and 8 show the simplest form of construction of the machine. For the platechains 5 and 6 cylinders 23 and 24 are substituted in the upper surfaces of which the molding grooves are cut. The cylinders 23, 24 rotate in the direction of the arrows.

Only the top cylinder 23 executes a transverse shifting movement, but both cylinders might be made to execute such transverse shifting movement. The driving gear is similar to that shown in Figs. 3 and 4.

Figs. 9 and 10 show a form of construction in which a plate-chain 5 cooperates with a" grooved cylinder 24. The operation is the same as in the other forms of construction described and shown.

The machine is designed not only for the production of seamless sweetmeats 'but it might also be used for the production of seamless bodies of other plastic mass for instlance for the production of clay balls or the li (e.
